AIWA XK-5000

Commentary

A cassette deck with AMTS and pure / amorphous 3 heads.

Equipped with AMTS to suppress tape vibration.
The cassette half is surface-pressed with a uniform pressure of approximately 1 kg instead of point contact to minimize tape vibration and achieve stable tape travel. This greatly reduces modulation noise and improves left / right separation to reproduce cloudless sound in all bands and improve the sense of orientation.

It employs a 3-motor closed-loop dual capstan mechanism, with one dedicated motor for FF/REW and one dedicated motor for the capstan. In addition, high-precision processing has been applied to the heavy class flywheel made of zinc die cast to ensure stable driving.
In addition, the capstan adopts a frequency separation type in which the shaft diameter of the two capstan is changed, eliminating frequency overlap and preventing resonance.

The recording and reproducing head uses a PC-OCC wound pure amorphous head.
The head material is 12-layer laminated pure amorphous with good magnetic properties. The recording head uses a 4-micron wide-gap head, and the reproducing head uses a 0.8 micron narrow-gap head.
High-purity PC-OCC is used for the winding.

Double-gap Sendust head is used for the erasing head.

The head block uses a 30g zinc die cast head block to reduce modulation noise by suppressing fine head vibration. In addition, the head block is equipped with a bias shield to reduce bias leakage from the recording head wire to the reproducing head wire and signal leakage, enabling a reduction of approximately 40 dB.

By adopting a super-bias recording system and shifting the recording bias frequencies to twice that of conventional models, it is possible to record with less distortion in the high frequency range under the influence of Tsutomu Dainyu.

It is equipped with a manual calibration function to bring out the tape performance. The built-in oscillator is set to 400 Hz and 10 kHz for wider frequency adjustment.
At the time of calibration, the level meter is expanded to 0.5 dB steps, enabling more accurate calibration.

Equipped with Dolby HX Pro with discrete configuration.
In the Dolby HX Pro, the bias amount is adjusted to the optimum state in units of 1/1000 second in accordance with the amount of the high-frequency signal, thereby suppressing over-bias caused by the high-frequency component acting as a bias current.
Also, Dolby HX Pro works only when recording, so it is also effective when playing on a non-loaded cassette deck.

Equipped with Dolby B/C NR using low distortion factor IC.

Uses a power assist cassette door.

Equipped with 3-mode display.

Quick response AI mechanism is adopted.

It is equipped with a music sensor which is convenient for starting the music.

Equipped with CD/DAT direct in.

Equipped with a linear time counter with pre-end winker.

It is equipped with a 000 return function that can return accurately from any position to the counter display "0".

Equipped with an auto monitor.

Equipped with a quick review / cue system.

Equipped with a follow / follow / mute function.

Wireless remote control is included.
